12 Claims.

This invention relates to improvements in automatic bookbinding machinery and has reference more particularly to a machine for making covers for bank pass books.

Bank pass book covers are provided with rectangular Cardboards on each side to stiien them and these are covered with leather, cloth or simin lar material glued to the Cardboards and which forms the outer finished surface of the book. The

leather or cloth covering connects the two sides.r

and forms the hinge. The leather or cloth cover or jacket is cut of such size that it can be folded over the outer edges and the ends of the card-A boards so as to produce a finished appearance.

-In assembling the jacket andthe Cardboards to form the cover, one side of the jacket is covered with glue and the Cardboards are then place on theglued surface in such a position as to leave the right amount of margin to permit the jacket to be turned over the edges .of the cardboard and far Venough apart to provide the necessary hinge.

` It is an object of this invention to produce a machine that will place the stiiening Cardboards onto the freshly glued cover or jacket, accurately ask to position, and to do this quickly and automatically.

Another object of this invention is to produce amachine that will automatically assemble the cover parts and deliver them to a conveyor.

. A further object is to produce a machine of such design that the freshly glued jackets can be readily positioned against suitable stops and retained in such position until the stiifening cardboards have been applied.

A still further object is to produce a machine that can be used forassembling covers of diierent sizes.

Another object is to produce a machine for the purpose specified, that will operate quietly and which shall be simple and inexpensive.

v The above and other objects that may become apparent as the description proceeds are attained b-y means of a combination and arrange-` ment of parts that will now be described in detail and reference for this purpose will be had to the accompanying drawings in which the machine has been illustrated in its preferred form and in which .Figure 1 is a side elevation of the improved book binding machine;

Figure 2 is a general plan view thereof;

Figure 3 is, a fragmentary section to an enlarged scale,taken along line 3,-f3, Figure 1;

Figure 4 is a fragmentary section to an enlarged scale, taken along line 44, Figure 1;

Figure 5 is a fragmentary section to an enlarged scale, taken along line 5 5, Figure 4, with the carriage just about to strip a card from the maga- 6 zine, shown thus for clarity; and

Figure 6 is a plan View of the carriage, showing certain details of the construction.

In the drawings reference character l denotes, as a whole, the frame that supports the various l0 elements of the'machine, 8 is the main driven pulley and 9 a belt delivering power from any source, not shown. The shaft I@ on which pulley 8 is non-rotatably mounted, carries cams I2 and I3 and rotates them in the direction indicated by 15 the arrow, and is journalled in bearings I4.

Cam I2 bears against rocking beam I5 which is journalled for oscillation about pivot I6, and is held in following contact with cam IZ by springs Il. The upper end of the beam is provided With a clevis I8 to which is attached one end of a cord or belt I9 that passes over pulleys 2U and 2| on the frame l and back over pulley 22 on the beam and is anchored to the latter at 24,' by means of spring 23, Figure 3.

Elevated supports 25 hold card magazines 26 above a reciprocating conveyor or carriage 2l) which slides in grooves 35. Carriage 2l is attached by means of an arm 28 and clamps 29 toA cord I9. Carriage 2'! carries a plate 30 on which 30 are mounted stripper lugs 3l, and a guide block 32, which are adustable as to their exact location, by means of slots and screwsr as shown at 33 and 34 respectively, in Figure 6. Plate 30 is also adjustable on carriage 2l by similar means 36.

'Ihe cardboard magazines 26 each comprise a housing 37, two vertical guides 38, horizontal guide iianges 39 and a delivery clip 40. At the lower end of clip 40 a tongue 4I is bent outwardly and upwardly and a pair of tongues 42 40 are bent inwardly. Cardboards 43, to be used in the book covers, are stacked in the magazine and restv on anges 44' at their sides and on tongues 42 at one end.

The ends of each magazine or housing 31 45 are each provided with a cleat 31a, secured in l place by rivets, or spot welding, and serve to support the magazines from the upper edges of members 25 (see Figure 5).

The feed clip 40 is supported from the upper 50 edge of the front wall of the magazine by a bent over tip 45 to the outer surface of which a boss 46 is attached. A slide 4l (Figure 4) has each end provided with a downwardly extending tongue 41a which slides in the spacebetween the 55v y low the tongue 4I bars 25 and 25a and with similar offset tongues 41h. The upper edge of slide 41 is provided with two inclined cam surfaces 48 that engage the bosses 46, when the slide is moved towards the right so as to hold the feed clipsl in elevated and inoperative position.

Cam I3, Figure 1, engages an arm 119 attached to lever 50, which is pivoted at I and has a U clip 52 at its upper end. The clip engages the bent-down end 53 of shaft 54, that is: journalled in brackets 55 and to which the arms 56 are rigidly attached. A cross other ends of arms 56 and carries screws which are pointed on their lower ends.

A curved nger 59 is attached to bar 51 and its end is bent downwardly and pointed. A resilient rider 60 is attached to one end of bar 51 and extends downwardly slightly farther than the points of screws 58, and finger 59.

A pulley 6I is carried by the main shaft Ill and drives a crossed belt 62 to rotate conveyor roller 63 in the opposite direction soY that conveyor belts 64 will carry the book covers away from the machine in the direction indicated by the arrow.

In operation the carriage 21 reciprocates, passing under the cardboard magazines in opposite directions at each cycle and is driven by the cord I9 and beam I5 as this is acted upon by cam I2. The spring anchorage 23,V of the cord permits it to change length slightly at each stroke and the particular shape of the cam I2 causes the carriage to stop for a short period of time at each end of its path.

The operator thus has time to place a freshly glue-coated jacket on the carriage plate 35, against the stripper lugs 3I and guide block 32 as shown in dotted lines at 65, Figure 6. As the carriage passes beneath the magazines the stripper lugs remove the lower cardboard 43a from each magazine and force it through opening 66 underneath the flange 39 and down onto the glued upper surface of the jacket.

Only the lowermost board projects down bewhich is raised slightly by the lug 3I as it passes below it, bringing the lowest board into place to be stripped from the magazine. Two boards,Y one from each magazine, are

thus placed on each jacket as shown in dotted` lines at 55a and 43h in Figure 2, at each forward stroke of the carriage. The boards are directed down onto the jacket through and by slots 66.

When the carriage reaches the extreme left hand end of its reciprocating cycle, cam I3 functions to permit the arm I9 to drop slightly thereb-y permitting lever 50 to move clockwise whereupon arms 56 drop and place the points of screws 58 and finger 59 onto the semi-finished cover assembly. The rider 5I] contacts the carriage plate 30 to prevent the points from passing en.- tirely through the boards.V Points 58 together' with the nger 59, which falls on the jacket, between the cardboards, hold the work stationary as the carriage returns toward the right. As the carriage is moved from under the cover, it falls onto conveyor belts 64 to be taken away to the next operation.

The lugs 3l and guide 32'as well as plate 30 can be adjusted for varioussizes of boards and jackets, and by raising the clips 4U outof range of the stripper lugs by means of slide 41, the operator can stop the machine from delivering cardboards.

It will be seen from the above that by means l. of the simple mechanism described 'and shown` bar 51 connects` the in the drawings, the operator merely feeds the glued jackets onto the reciprocating conveyor or table whenever it returns to its extreme right hand position and the machine will then strip one cardboard from each magazine and deposit it in a predetermined position thereon. The jackets with the cardboards attached thereto are then deposited on the conveyor belts and transferred to a station where another operator turns the edges of the jacket about the edges of the cardboards so as to finish the covers.
